Inventor: WADA TADAYOSHI
IPC: B21B45/00
Filed: 1982-03-29
Abstract: PURPOSE:To obtain the descaling agent excellent in adhesiveness and easy to perform after-treatment, by using an adhesive agent prepd. by adding Na2O. 3SiO2 and optionally Al or glass powder to an alkaline earth metal compound. CONSTITUTION:To 100pts. an alkaline earth metal compound, 1-30pts. an adhesive agent comprising Na2O.3SiO2 or prepd. by adding 1-10% Al and/or glass powder to Na2O.3SiO2 is added. This composition is formed into slurry by adding water to it, to obtain the antiscaling agent. When this descaling agent is applied to the surface of a steel piece being transferred at a high speed while being held as such at a high temp. by a spray or laminar flow method, it instantaneously forms the film of steam, changes into water drops and rotates on the surface. It is not difficult to apply it to the surface. When the proper amount of the descaling agent is used, its concentration is increased, its adhesiveness is remarkably enhanced, and the excellent effect of application is exhibited. Consequently, the after-treatment of the steel sheet is facilitated by the application of said descaling agent.

Title: Barrel type multistage pump
Inventor: IINO MINORU
IPC: F04D1/08
Filed: 1982-03-29
Abstract: PURPOSE:To easily assemble and disassemble a barrel type multistage pump by manufacturing a stage and a barrel with materials differing in their coefficients of thermal expansion and properly providing a gap between the stage and the barrel. CONSTITUTION:When a pump is operated under a cryogenic remperature, the internal diameter of a barrel 5 is shrunk compared with the external one of a stage 4, and the external peripheral surface of each stage 4 and the internal peripheral surface of the barrel 5 are joined with each other and sealed. On the contrary, in a pump operated under a higher temperature, if the stage 4 is manufactured with a material having a larger coefficient of thermal expansion than that of the barrel 5, the stage 4 and the barrel 5 are joined with each other and sealed since the stage 4 is still more thermally expanded than the barrel 5, so that it is possible to previously prevent a high pressure fluid to leak out.

Abstract: PURPOSE:To enhance the diagnostic accuracy and reduce burden of an operator by restructuring an image using data after judgement of each threshold value, extracting a contour image, smoothen this extracted contour image, and by calculating error in the area of the contour image for each slice smoothened. CONSTITUTION:Data stored in a recorder 3 is read and converted by a data converting device 4 into the form of cynogram, and a threshold value judging device 5 makes judgement of threshold value for each cynographic view. The cynogram indicating only positions corresponding to the contour is sent to an image restructuring device 6 to undergo back projection treatment. There an image is restructured, which is formed with a number of couples of parallel lines differently directed. The contour is extracted by a contour extracting device 7 to produce an image consisting only of contour line. A smoothening device 8 smoothens this image to produce a contour image drawn with smooth curves. An error sensing device 9 calculates the mean square error for the area in contour line of a number of slices as object to be compared with respect to the area in contour line of the reference slice. The slice of contour image with least error is judged to be the same slice as the reference slice.

Filed: 1997-02-18
Abstract: PROBLEM TO BE SOLVED: To prevent an output shaft form being placed out of a gear box by accidental pressing, in the inner end part of a metallic output shaft which an output gear is pressed in, a metallic stopper plate whose thermal expansion coefficient is next to that of the output shaft. SOLUTION: The rotational movement of a rotor assembly 7 is decelerated by a reduction gear train which is constituted of an intermediate gear 10, reduction gears 12, and an output gear 14, so that the rotational movement decelerated by an output shaft 13 protruding to the outside of a gear box 3 is outputted. Before the assembly of the output shaft 13 into the gear box 3, the output gear 14 is first pressed into an inner end part 13a of the output shaft 13, a stopper plate 15 constituted of metal whose thermal expansion coefficient in next to that of the output shaft 13, such as copper alloy, is pressed into the inner end part 13a. Therefore, even if a temperature change occurs, the fixture between the output shaft 13 and the stopper plate 15 is prevented from being loosened.  It is thus possible to prevent the output shaft 13 from being placed out of the gear box 3, even if a strong external force works upon the output shaft 13 in an arrowhead Y-direction after assembly.

Title: Dc-stabilized power-supply circuit
Inventor: FUJISAWA MASANORI
IPC: H02M3/155
Filed: 1993-02-16
Abstract: PURPOSE:To make the response to output current excellent and to make efficiency excellent regardless of input voltage by detecting the voltage of DC power with a switching circuit, and keeping the dropping voltage at a transistor at the constant voltage corresponding to the base-emitter forward dropping voltage. CONSTITUTION:In a switching circuit 30, the input power at a DC voltage Vi is received, switching is performed with a switching transistor Q2 and switching power of a voltage Vd is formed. The switching is performed with the differential voltage between the first voltage to be detected Vp and the second voltage to be detected Vo. A filter circuit 40 smoothes the switching power of the voltage Vd and outputs the DC voltage Vp. A three-terminal regulator 2 generates the second DC power of the DC voltage Vo by decreasing the voltage Vp of the first DC power. Then, the dropping voltage at the transistor Q1 is kept at the constant voltage corresponding to the dropping voltage in the base-emitter forward direction with the switching circuit 30. Thus, the power loss in the transistor Q1 is decreased.

IPC: H04N1/04
Filed: 1989-03-01
Abstract: PURPOSE:To keep the continuity of a memory read clock signal and to obtain a good picture quality by providing a delay means which successively delays a series picture signal with the clock signal to output plural delay picture signals and a selecting means which selects one signal. CONSTITUTION:A P/S converter 5 takes in picture signals corresponding to N-number of picture elements read out from a memory 4 in parallel and converts them to a series picture signal by a memory read clock signal(RCK), and this signal is inputted to a shift register 8. The register 8 shifts the picture signal of one picture element as the unit by a clock signal (CK) and outputs an 8-bit parallel picture signal whose delay time is extended by every one clock, and this signal is inputted to a data selector 9. A latch 10 latches the value of a counter 2 by a synchronizing signal(SYNC) and inputs it to the select control terminal of the selector 9, and then, the selector 9 selects the output of the register 8 designated by this designation and outputs it as a modulated signal from a terminal 7. Thus, the RCK continuously keeps a certain period to obtain the signal of good picture quality.
